This paper aims at shedding light on what students can "construct" when they learn science and how this construction process may be supported. Constructivism is a pluralist theory of science education. As a consequence, I support, there are several points of view concerning this construction process. Firstly, I stress that constructivism…

This study compared the effects of a constructivist-visual mind map teaching approach (CMA) and of a traditional teaching approach (TTA) on (a) the quality and richness of students' knowledge structures and (b) TTA and CMA students' perceptions of the extent that a constructivist learning environment (CLE) was created in their classes. The sample…

This paper draws attention to the literature in the areas of learning, specifically, constructivism, conceptual change and cognitive development. It emphasizes the contribution of such research to our understanding of the learning process. This literature provides guidelines for teachers, at all levels, in their attempt to have their students…

The main purpose of the study was to compare the effectiveness of 5E learning cycle model based instruction and traditionally designed chemistry instruction on 10th grade students' understanding of state of matter and solubility concepts. In this study, 119 tenth grade students from chemistry courses instructed by same teacher from an Anatolian…

Explores the extent to which student questions are indicative of understanding as well as strategies for encouraging questioning. Student questions are categorized as consolidation questions, exploratory questions, and elaboration questions. (DDR)

This study, based on constructivist learning theory, examined how effectively preservice chemistry teachers (N = 43) can be educated to think flexibly and to reorganize their thinking in a way that may complement diverse ways students approach the subject domain. The teacher's cognitive structure was assessed prior to and after a conceptual change…

Describes the use of concept maps as a metacognitive tool to help chemistry teachers and learners improve teaching and learning. Concept maps were used in response to changes in the conceptions of the nature of scientific knowledge and in how learning occurs. Concept maps are valuable in documenting and exploring the restructuring of conceptual…

Reports on a study that addresses the implications of instructional strategies that are used to create cognitive disequilibrations to achieve conceptual change. Discusses several difficulties in the application of such conceptual change strategies. Contains 31 references. (DDR)

Constructs the philosophical background and underpinnings of the Science Education Portfolio Instruction and Assessment (SEPIA) project. Explains that students must develop skills in order to participate in epistemic interchanges. They must also be provided opportunities and materials to develop those skills. Contains 29 references.

Writing can be a powerful tool for learning biology. Writing assignments in biology could help students personalize and understand the biology knowledge they are studying. In this article, the authors present the "Botanical Sense of Place" (BSP), a convenient and easy-to-use writing template that they developed to elicit and probe students' prior…

Assessed the impact of elementary science experiences on the development of sixth-graders' epistemological views. Found that, compared to students in a traditional science classroom, those in a constructivist classroom developed an epistemological stance toward science that focused on the central role of ideas in the knowledge acquisition process.…

The main purpose of this study was to explore the effects of long-term constructivist-oriented science instruction on elementary school students' process of constructing cognitive structures. Furthermore, such effects on different science achievers were also investigated. The subjects of this study were 69 fifth graders in Taiwan, while they were…

The purpose of this study was primarily to explore the effects of constructivist-oriented instruction on fifth graders' cognitive structures about biological reproduction. Furthermore, such effects on different science achievers were also investigated. The subjects of this study were 69 eleven year olds in Taiwan, who were assigned to either a…

This paper attempts to create a vision of what it would be like to teach for understanding, to adopt the view of learner as constructor of his or her own understanding, and to share in the creation of an environment for reconstructing students' understanding and reasoning. Such a program is based on assumptions about the cognition of learners,…

The assertion that there is a social component to children's construction of knowledge about natural phenomena is supported by evidence from an examination of children's classification schemes for plants. An ethnographic study was conducted with nine sixth grade children in central Texas. The children classified plants in the outdoors, in a…
